Let the Obsession begin. Again. This time, the entire forces of the netherworld have overrun Earth. To save her, you must descend into the stygian depths of Hell itself! Battle mightier, nastier, deadlier demons and monsters. Use more powerful weapons. Survive more mind-blowing explosions and more of the bloodiest, fiercest, most awesome blastfest ever! Play DOOM II solo, with two people over a modem, or with up to four players over a LAN (supporting IPX protocol). No matter which way you choose, get ready for adrenaline-pumping, action-packed excitement that's sure to give your heart a real workout.
Version 1.2 Final! Single-player, single map, compatible with vanilla Doom. As always, clean up the base from the infestation and dish out all the punishment on the bosses in the end. Tested with GZDoom and Chocolate Doom. Should be (in theory) compatible with all Doom ports.
